1numerous practices have been developed to reduce including reducing or eliminating tillage, managing irrigation to reduce runoff, and using terracing or contour planting.
2 foods labeled as “natural” are required to contain at least 50% organic ingredients.
3 the genetic changes in genetically modified plants cannot spread to wild populations or affect natural biodiversity.

1. Erosion

The erosion is a very big problem in the agriculture. This problem is especially big where there are slopes, or the surface layer of the soil is very loose. In order to stop the degradation of the soil, thus to be able to use it on the long run and to have good yields, the people have started to come up with multiple solutions. One of the methods has been to reduce runoff from the irrigation, as with it, the top, most fertile layer of the soil is washing away. By using methods where the water falls on the land at a more direct angle, the soil is not washed away. Another method, used at places with steeper slopes, is the terracing. This method is basically creating terrace like flat parts on the slopes, and by doing so, the soil is preserved as it is flat, instead of being on a slope and constantly exposed to runoff and wind.

2. False

The label ''natural'' on the foods is a term that is very often used by the companies, but legally it is not really accepted and regulated. The companies use this term so that they can attract more costumers, leading them to believe that the product doesn't have any artificial additions. This is not true though, as pretty much all foods labeled like this do have artificial additions to them, and since it is legally not regulated as to what should the percentage of organic food be in them, there's not really a standard for it.

3. False

The genetically modified plants are very useful for the elimination of malnutrition among the humans, but on the other hand they are very dangerous for the biodiversity. While these plants will in general not reproduce with the wild ones, the dangers are that these plants are able to easily out-compete the wild ones. The genetic changes in these plants provide them with advantageous traits, such as being larger, producing more seeds, being resilient to harsher weather conditions, which leads to easily take over the wild populations and replace them.
